<ol type="1">
|
|
<li>Expand the <span class="bold">Server administration </span>category
|
|
in the navigation area. Click <span class="bold">Manage unique attributes</span>.</li>
|
|
<li>Select the attribute that you want to add as a unique attribute from the <span class="bold">Available attributes</span> menu. The available attributes
|
|
listed are those that can be designated as unique; for example, sn.</li>
|
|
<li>Click either <span class="bold">Add to cn=localhost</span> or <span class="bold">Add to cn=IBMpolicies</span>. The difference between these
|
|
two containers is that cn=IBMpolicies entries are replicated and cn=localhost
|
|
entries are not. The attribute is displayed in the appropriate list box. You
|
|
can list the same attribute in both containers.
|
|
<a name="wq191"></a>
|
|
<div class="notetitle" id="wq191">Note:</div>
|
|
<div class="notebody">If an entry
|
|
is created under both cn=localhost and cn=IBMpolicies, the resultant union
|
|
of these two entries is the unique attributes list. For example, if the attributes
|
|
cn and employeeNumber are designated as unique in cn=localhost and the attributes
|
|
cn and telephoneNumber are designated as unique in cn=IBMploicies, the server
|
|
treats the attributes cn, employeeNumber, and telephoneNumber as unique attributes.</div></li>
|
|
<li>Repeat this process for each attribute you want to add as a unique attribute.</li>
|
|
<li>Click <span class="bold">OK</span> to save your changes.</li></ol>
|
|
<p>When adding or modifying a unique attribute entry, if establishing a unique
|
|
constraint for any of the listed unique attribute types results in errors,
|
|
the entry is not added or created in the directory. The problem must be resolved
|
|
and the command to add or modify must be reissued before the entry can be
|
|
created or modified. For example, while adding a unique attribute entry to
|
|
the directory, if establishing a unique constraint on a table for one of the
|
|
listed unique attribute types failed (that is, because of having duplicate
|
|
values in the database), a unique attribute entry is not added to the directory.
|
|
An error is issued.</p>
|
|
<p>When an application tries to add an entry to the directory with a value
|
|
for the attribute that duplicates an existing directory entry, an error with
|
|
result code 20 (LDAP: error code 20 - Attribute or Value Exists) from the
|
|
LDAP server is issued.</p>
|
|
<p>When the server starts, it checks the list of unique attributes and determines
|
|
if the DB2 constraints exist for each of them. If the constraint does not
|
|
exist for an attribute because it was removed by the bulkload utility or because
|
|
it was removed manually by the user, it is removed from the unique attributes
|
|
list and an error message is logged in the error log, ibmslapd.log. For example,
|
|
if the attribute cn is designated as unique in cn=uniqueattributes,cn=localhost
|
|
and there is no DB2 constraint for it the following message is logged:</p>
|
|
<p></p>
|
|
<pre class="xmp">Values for the attribute CN are not unique.
|
|
The attribute CN was removed from the unique attribute
|
|
entry: CN=UNIQUEATTRIBUTES,CN=LOCALHOST</pre><img src="deltaend.gif" alt="End of change" /><img src="deltaend.gif" alt="End of change" />
